DESCRIPTION

The BASI BTT791 Intelligent Explosion-proof Temperature transmitter with integrated sensor

according to ATEX-directive 94/9/EG, II 2GD, EExd IIC T6.The BASI isolated transmitter (1500VAC). This transmitter allows the user to: select sensor and input signal type (4 RTD types, 6 thermocouples and 3 linear signals); select and adjust input range; perform offset correction and device calibration; specify input ranges and output type (4 to 20mA or 20 to 4mA); select decimal point position and measuring unit; select output reaction on sensor break; adjust the digital filter. BTT791 transmitter is easy to program by using the specialized configuration software "TraCon". Thanks to its large capabilities

and low price, BTT790 can be very useful in different industrial applications requiring temperature conversion before following measurement and control.
